Diagnostic accuracy of two-dimensional echocardiography combined with Doppler echocardiography in neonates and infants with cardiac symptoms.

In a previous study the diagnostic accuracy of two-dimensional echocardiography was demonstrated. In a review of our clinical material from the last three years the additional value of Doppler echocardiography was evaluated. Doppler echocardiography did improve the diagnostic accuracy in a few groups of patients (patent ductus arteriosus, aortic stenosis and to some extent coarctation of the aorta). The main value of Doppler was however the possibility to obtain information about flow patterns, valve obstruction or regurgitation.
